Patented Nov. 25, 1930 UNITED STATES PATENT OFFICE FRANK o. BROEMAN, or CINCINNATI, OHIO, ASSIGNOR T0 ARTHUR SILBERSACK, or CINCINNATI, OHIO CLEANING POWDER No Drawing.

The water in use by many cities contains certain calcium salts either with or without iron salts, which gradually make an unsightly deposit when used in porcelain watereloset bowls and other similar vessels, in which the water isused.

The object of my invention is to provide a highly eificient dry powder which, when deposited upon water, will be held in suspension for a time and gradually settle therethrough to the bottom and rest upon the surface of the watercloset bowl, or other vessel, and when so applied will remove such deposits without injuring the vessel and without any inconvenience or danger to the person using the powder.

The removal of such deposits by hydrochloric acid, or similar liquids, is objectionable on account of the unpleasant odors produced in their use. Furthermore, the acid must be applied very skillfully and with great care by the user and even then the porcelain coating is apt to be damaged thereby.

Another disadvantage of such acids is that they are of such strength as to dangerously aiiect the skin of the user when accidentally coming into contact therewith.

These objections are avoided by the use of my invention.

The objects of my invention are to provide a owder which will remain in its ori inal lyiateinlle con amer. SllCl as wood,

tire body of water as it settles to the bottom upon the entire surface of the bowl, or other vessel to be cleaned; and to provide such a powder havin the ualities f bleaching and deordorizmg, as well as cleaning and pollslnng the surface oFthe vessel.

My novel powder, which cleans, deodorizes, disinfects and sterilizes at the same time, is composed of substantially the following ingredients: 15% of or anic matter, such as finely dividemticlegmn mm Ztof eac 1mg pow suc 1 as c 1 ormated lime, ll% of potassium chloride and W637QQ9H111H1 These ingredients are thoroughly ground, mixed and commingled and when so treated form an absolutely dry powder which will remain in that condition under usual atmospheric and temperature conditions.

This composition is articularl intended for use in cleaning urinal and toilet bowls and vitreous enamel of organic scum and lime and magnesium incrustations, and an other dirt or stains. It comprises a powder that does not settle immediately when sprinkled in the water but remains on the surface and allows action to be taken from the surface downward as the soluble ingredients dissolve. The organic matter, such as the sawdust or wood flour, serves the purpose of holding the soluble ingredients, such as bleaching powder, potassium chloride and sodium acid sulphate in suspension for suflicient time to permit of thorough saturation of the water and to cause a uniform and even deposit of the composition upon the entire surface being treated. These ingredients are preferably thoroughly ground to a fine powder in a ball mill and the organic material therein holds the chemicals partially in sus ension until thoroughly dissolved.

n important feature of this invention lies in the fact that this composition will not settle immediately when sprinkled or poured into water standing in toilet bowls but floats on the surface and allows the necessary dissolving action to take place from the surface downward.

5 While I have set forth particular proportions of ingredients, I do not limit myself thereto, nor to the use of said ingredients with the presence of other elements.

It will be understood, therefore, that the m exact proportions of the ingredients may be modified to correspond with varying conditions.

Applicant believes himself to be the first to combine and use the above combination of ingredients which more efficiently and thoroughly performs the desired functions than any other means heretofore employed for this purpose.

What I claim as new and desire to secure by Letters Patent is:

A composition containing a mixture of ingredients substantially as follows: 15% finely divided particles of wood, such as sawdust or Wood flour, 2% bleaching powder, such as chlorinated lime 20% potassium chloride and 63% sodium acid sulphate.
